Abstract Aim To infer phylogenetic relationships among Antirrhinum species and to reconstruct the historical distribution of observed sequence polymorphism through estimates haplotype clades lineage divergence. Location is distributed primarily throughout western Mediterranean, with 22 25 in Iberian Peninsula. Methods Plastid (83 trnS‐trnG 83 trnK‐matK ) nuclear (87 ITS) sequences were obtained from 96 individuals representing 24 species. Sequences analysed using maximum parsimony, Bayesian...

Reproductive barriers play an important role in the maintenance of species boundaries. However, to date, few studies have provided a detailed analysis reproductive isolation between or examined their importance maintaining identity. This is first study into pre- and post-zygotic Antirrhinum, based on mixed population with two that rarely co-occur. The revealed pollinator constancy preference poor hybrid seed viability were most isolating mechanisms. was practically complete by both barriers....

Several aspects of the reproductive biology Fumana juniperina were analyzed to find out whether delayed selfing occurs within a representative natural population in southwest Sardinia. Similar fruit set was obtained after autonomous, within‐flower, and between‐flower self‐pollination (0.35, 0.53, 0.46, respectively), cross‐pollination (0.45), control (0.39). Seed seed mass did not differ significantly between pollination treatments ($$P> 0.05$$). Autonomous favored at end floral anthesis,...

The germination behaviour of two Iberian endemic labiates, Sideritis pungens and S. chamaedryfolia selected from different habitats, ranging very humid to semi-arid, was studied under controlled experimental conditions. A factorial experiment, combining temperature regimes (10°, 15°, 20°, 25° or 30°C), photoperiod (total darkness 12 h light/12 darkness) pre-treatments (freezing, dry-heat, hot-water), designed analyze seed patterns dormancy processes. results obtained are in agreement...

Knowledge about the reproductive system of species inhabiting rocky habitats is scarce. The biology (floral biology, experimental pollination, insect visits, inbreeding depression, and seed predation) rupicolous Linaria cavanillesii was analyzed under field conditions. Self-compatibility revealed by high fruit set, mass in pollination experiment. Furthermore, results disclose that this does not need visitors for production since set after autonomous self-pollination similar to hand...

Cistus carthaginensis is one of the most endangered plants in Europe: at present there exist only a few individuals Murcia and Valencia (SE E Spain). To design an adequate conservation strategy able to avoid extinction this species, various aspects its reproductive biology were studied. The extreme rarity C. not related problems development and/or fertility pollen or ovules produced by existing specimens. Meiosis mother cells always regular chromosome segregation completely equilibrated male...

Antirrhinum is an Old World genus of up to 25 perennial taxa, mainly located in the western Mediterranean basin. A molecular analysis 24 taxa was undertaken using cpDNA sequences from trnT (UGU)-trnL (UAA) 5' exon region. The Kimura two-parameter model chosen calculate pairwise nucleotide divergence values between sequences, and a bootstrapped neighbor-joining dendrogram constructed distance matrix. Eighteen sites were variable across studied samples position 7 indels, ranging 1 bp, inferred...

Background: Nectar robbers in many plant species affect female reproductive success, usually decreasing the amount of seed produced by plants, which can populations persistence.Aims: To evaluate impact nectar on viability populations, we investigated effects robbing success a threatened snapdragon four over 2 years.Methods: We observed insect visitors and their behaviour quantified percentage robbed non-robbed flowers production fruits seeds.Results: The results showed degree variation among...

The surprising discovery of a population new species Antirrhineae (Plantaginaceae) has also given rise to the description genus situated in subtribe Maurandyinae: Gadoria falukei. This is supported by characteristics flower, pollen grains, seeds and capsule, phylogenetic results based on DNA sequences. endemic from Sierra de Gádor, Almería, Spain. Scanning electron microscopy was used explore micromorphology indument, seed grains ornamentation. Additionally, chromosomal number, preliminary...

Abstract Fumana is a diverse genus of the Cistaceae family, consisting 21 currently accepted species. In this study, nuclear (ITS) and plastid ( matK , trnT‐L ) molecular markers were used to reconstruct phylogeny estimate divergence times, including 19 species . Phylogenetic analyses (Bayesian Inference, Maximum Parsimony Likelihood) confirmed monophyly did not support infrageneric divisions previously established. The results four main clades that group differ in vegetative reproductive...

Fumana ericifolia belongs to the family Cistaceae, in which all perennial species previously studied have been reported be self‐incompatible and xenogamous. Here we show that F. is self‐compatible autogamous. Its flowers last only four eight hours produce a small amount of pollen ovules. Self‐pollination depends on changes relative position stigma anthers, triggered by abscission petals; this turn causes closing sepals, push anthers onto stigma. Pollen remains highly viable germinable, keeps...

La jara de Cartagena fue elegida en 2024 la planta amenazada del año el concurso anual SEBiCoP. Seguramente se trata taxón flora española que ha llegado a un mayor nivel amenaza y también protección, al ser única declarada Situación Crítica por Ministerio para Transición Ecológica Reto Demográfico. Antes pasó todo tipo situaciones. Abundante principios siglo XX, considerada extinta décadas después, descubierto solo individuo los años 80 (a casi 300 km localidad original) recientemente...

Typification of the names Antirrhinum barrelieri Boreau, A. controversum Pau and litigiosum (Antirrhineae, Plantaginaceae) is needed to clarify use concept these three names. The origin a misinterpretation name , which conditioned subsequent names, discussed. previous ‘lectotype’ designated by Rothmaler from Barrelier's illustration shown be ineffective, being contrary Art. 9.12 ICN therefore lectotype syntype preserved in herbarium Muséum des sciences naturelles d'Angers (France) at ANG....
